Ellipsoid.InverseFlattening Property
Gets the inverse flattening 1/f (dimensionless).
Thread safety: This property is thread-safe.
Syntax
public System.Double InverseFlattening { get; }Property Value
Type: System.Double
Default: Must be specified in constructor.
The inverse flattening, a dimensionless number.
Default: Must be specified in constructor.
The inverse flattening, a dimensionless number.
Remarks
The inverse flattening, 1/f, is defined to be a/(a-b), where a is the equatorial radius and b is the polar radius. For the Earth, the inverse flattening should usually be between 293.0 and 309.0. (The Wgs84 value is 298.257223563.)
If you need to implement an ellipsoid specified by the equatorial radius a and the squared eccentricity e², then compute the inverse flattening by
1/f = 1 /(1 - sqrt( 1 - e²))
